Three-phase AC steel-making electric arc furnace is mainly used for smelting high-quality carbon steel and various alloy steel and ferrous metals. According to power match is divided into ordinary power, high-power and ultra-high-power electric arc furnace. 10t capacity EAF and above 10tons all with the hydraulic drive, hydraulic lifting system is imported electrode proportional valve control, feeding methods is Rotating open-top feeding ways.  The full set of equipment design reasonable reliable operation, smelting energy-saving advantages.

Three-phase AC electric arc furnace with the main technical advantages:

1. Use of advanced imported hydraulic proportional valve lift control system of electrodes, electrode breakage rate is low.

2. In a large furnace shell with water-cooled furnace shell and the split design ensures optimum refractory performance.

3. The use of advanced triangle short network layout, so that stable operation of electric arc furnace and the electrical conductivity of three-phase unbalanced system impedance is less than 5%.

4. Electrodes using atomizing spray device, to reduce electrode consumption.

5. EAF all-hydraulic drive, stable operation is safe and easy to operate.

6. With equipment move-point video surveillance systems, equipment movement is safe and easy operation to run.
